Whenever the late summer and early autumn after a rain, a cluster of mushrooms will be ground out. Mushrooms growing on the prairie include the almonds of Tricholoma mongolicum, the algae of T.gambosum, the alfalfa mushrooms of the genus Clitocybe gigantea, Edible mushrooms. After the mushrooms are collected, they are transported to the Zhangjiakou mushroom processing factory and processed through rigorous processes into finished products, which are then delivered to domestic and foreign markets. As the distribution center in Zhangjiakou City, it is collectively referred to as “Mushroom.” Tricholoma growth and development needs lower temperature, hi slightly acidic soil, dam
